PLURAL-FLUID NOZZLE AND METHOD OF LIQUID DISTRIBUTION.

Application led J' une 3,

To all whom 'it may concern.'

Be it known that I, LEE H. PARKER, a citizen of the United States, and a resident of Boston, in the county of Suolk and State of Massachusetts, have invented an Improvement in Plural-Fluid Nozzles and Methods of Liquid Distribution, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to plural fluid nozzles and yto a method of plural liuid d istribution.- l

In order that the principleof the invention may be readily understood, I have, in the accompanying drawings, represented the preferred formiof nozzle embodying my invention and will set forth the best mode known to me for practising the same.

In the drawings.

Fig. 1 is a vertical transverse section of a nozzle constructed in accordance with my invention;

Fig. 2 is a side elevation ofthe construction shown in Fig. 1, but with the upper or terninal memberof the nozzle removed; an

Fig. 3 is a plan view of the construction shown in Fig. 2.

Referring more particularly to the drawing, I have therein represented a terminal nozzle casing 1' having a discharge orifice 2, and I osition therein an inner core member 3 whic may be integral with the casing 1 or structurally separate. p While it may be of any suitable character, it is preferably of a form providing -for an inner and desirably axial jet within the central longitudinal passage 4 and one or more surrounding jets which are formed by the spirals or helices 5. Generally speaking, the character of the said core may be similar to that of the corev provided in the nozzle of the Eneas Patent No. 1,239,168, dated September 4, 1917,

though any other suitable construction may be employed providing an inner jet,-de sirably a centraljet,-and one or more surrounding jets.

In accordance with the invention herein `set forth, I employ two different fluids, one or both of which may be a liquid such as water, and I introduce one of said fluids through the centralpassage 4 and the other of sald fluids is subjected to a whirling .fluids or the two liqui 1920. Serial No. 386,244.

-fluids from any desired sources. These two fluids may beof the same character, as, for example, water, but received from different sources or differmg 1n ysome'way'from each ,other, or ifv desired the two fluids may be respectively air and water, or water and steam, or some other fluid and liquid.

The partition 9 is preferably threaded as indicated at 14 for the reception of a pipe or tube 15 which extends longitudinally of the nozzle member 6 and desirably centrally thereof, and is internally threaded at its upper end at 16 for the reception of the lower externally threaded end 17 of the core .member 3. Interiorly the pipe 15 ma be of any suitablecharacter, but desirab y I'- provide means such as the spiral 18 whereby the fluid or liquid passing therethrough may be given a whirling action. Such whirling' action may be continued through or into ythe central passage 4 of the core member 3,;as

for example by providing a spiral member in said passage or by rifiing the same, but 9U in the present embodiment of my invention the passage 4 is represented as smooth or without a spiral. i'

In accordance with my invention, the fluid or liquid entering the passage 10 passes through the pipe 15 where it may or may not be given a rotary or whirling action, and after passing through the passage 4 it enters the mixing chamber 19. The fluid or liquid entering the passage 11 surrounds 100 the pipe 15 and when it reaches the core 3 it receives a whirling motion due to the spirals, vanes or helices 5, so thatsuch fluid or liquid enters the mixing chamber 19, where it becomes thoroughly mixed with the fluid or liquid entering said chamber -through the inner passage 4. The two s after having become thoroughly mixed within the mixing chamber 19 issue through the orifice 2 in a spray 110.

though speciic terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope or the invention being setl forth in the following claims.
